What does it mean if you are walking normal one moment.....?

Question

Then you get so dizzy that you feel disoriented and begin to walk sideways, then you are fine again a moment later?

Answer 1

did you get up from sitting a long time? sometimes the blood rushes to the brain and we get light headed...

are your working your self to much and you need to relax a bit more  

Answer 2

Well, my first thought knowing you is that you are sleep deprivied, seriously.. and need to rest.. you know that already though.. sometimes our body tries to force us to shut down and get the rest we need.. and if you don't.. it will continue different things, including making you sick, just to get you to take the time to rest..

More serious issues could be at play like blood pressure, blood sugar, etc.. which also can be affected by lack of sleep.. so, honey bunny... Get some sleep!!! And you'll feel much better.. :)
